Answer to Question 1

ANS: A
Swallowed food is moved from the esophagus to the stomach by peristalsis, not retropulsion. Haustral segmentation occurs in the small intestine. Defecation is the process of eliminating stool from the rectum.

Answer to Question 2

ANS: B
The parietal cells secrete hydrochloric acid. The chief cells secrete pepsinogen. Zymogenic cells do not secrete acid. Epithelial cells line the GI tract and do not secrete acid.

This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition.
